Description
Summary:CdS has a wide range of applications for explorations of its optical and electrical behaviors. A microplasma cell with a CdS electrode has been constructed. The measurements on discharge currents under various gas pressures, interelectrode distances and excitation voltages have been studied theoretically and experimentally. The 2D electron densities under different parameter ranges along the gas discharge volume have been examined. The structural and optical features have been analyzed using scanning electron microscopy, atomic force spectroscopy and Fourier transform infrared spectroscopy for complementary information. Experimentally, as an additional optical test, CVC measurements have also been performed under IR stimulation to verify the infrared sensitivity of the sample. The CdS cathode sample has been damaged by the high energetic current value around 10 −1  A following the plasma transition from the glow to the arc.
